Awesome post thank you.
Two of my Fwb sports have now arrived back, actions from blueing by Colin maloy, stocks from Nathan for restoration.
Got to try three other sports at the BBS bash a couple of weeks ago, each having different tuning done to them. The most pleasant by far to use "for my tastes" was a simple v-mach drop in kit.
So when I get back from hols I will order one and see if it feels the same in mine, if it does I will order another.
